The Marine Strategy Framework Directive (MSFD) obligates all EU Member States to take the necessary measures to maintain or progressively achieve Good Environmental Status (GES) in the marine environment by the year 2020. In order to assist Member States (MSs) in the implementation of the MSFD, a MSFD Competence Centre (MCC, http://mcc.jrc.ec.europa.eu/) has been established at the Joint Research Centre, Directorate D – Sustainable Resources (Water and Marine Resources Unit). In the framework of the Administrative Arrangement No ENV C.2/2015/070201/705766 between DG Environment and DG JRC, Directorate D – Sustainable Resources, Water and Marine Resources, the development of a modelling toolbox has been initiated. This toolbox facilitates the online coupling of a hydrodynamic model with a lower trophic level model of the Black Sea ecosystem. It can be used for multi-annual simulations of past, present and future conditions in the Black Sea. The General Estuarine Transport Model (GETM) has been selected as reliable hydrodynamic model for the Black Sea’s simulations. The model is forced with atmospheric data from the European Regional Downscaling Experiment (EURO-CORDEX), river runoff from Global Runoff Data Centre (GRDC) and is initialised with temperature and salinity 3D fields coming from the project MEDAR/MEDATLAS II. A new Black Sea Ecosystem Model (BSEM) is linked via the Framework for Aquatic Biogeochemical Models (FABM,) with the hydrodynamic model. The coupled physical-ecosystem modelling system has been calibrated and validated for the Black Sea conditions. The numerical experiments indicate that the biogeochemical components of the model rather successfully reproduce the main features and state variable evolution in the Black Sea ecosystem: the growth in phytoplankton biomass and changes in seasonal cycles of the main ecosystem components. It is however shown, that the physical processes are of fundamental importance for a reliable reproduction of seasonal and inter-annual changes in the ecosystem.
